Explanation

ACE577C is a series of low dropout voltage and low power consumption regulator. Its application circuit is

very simple, which only needs two outside capacitors. It is composed of these modules: high accuracy

voltage reference, current limit circuit, error amplifier, output driver and power transistor.

Current Limit module can keep chip and power system away from danger when load current is more than

180mA.

ACE577C uses trimming technique to assure the accuracy of output value within±2%, at the same time,

temperature compensation is elaborately considered in this chip, which makes ACE577C

’s temperature

coefficient within ±100ppm/℃。
